Do not use Windows 8.1, lots of issues for mining. Try to install 14.4 driver, usually it works better for HD6xxx GPU. As for current setup it seems that your intencity is too high, try to lower intencity until GPU start to hash. I'll try ten times lower performance for start to be sure that it is not an issue.

Hello, did that, xmr-stak does not even detect the card now. But xmrig does and it detecs more available memory than before with the newer driver.

Thanks,
